Hill soils that are present at foot hills of Aravallis are also called as lithosols. Dungarpur, Banswara & parts of Udaipur, Chittorgarh districts have such soils. These soils are reddish in colour with granular/crumb structure & well drained. These soils have rich content of iron-oxide and devoid of calcium salts because calcium salts soluble in water and are easily washed away. Soils are suitable for maize, chillies, wheat, barley and rapeseed cultivation.

The crystalline granites produce non-laterite type of soils in drier areas. These include tropical sandy like desert soils and clayey soils which are gravelly in some places 

Ferruginous red soil which occupies central and southern part of Udaipur district and the entire Dungarpur district is poor in Nitrogen, Phosphorus, Humus. Red soil had been formed from ancient crystalline and metamorphic rocks. The characteristics of this soil are light texture, porous and friable structure. 

Saline sodic soils that are found in Pachpadra, Sambhar, Ranns of Jalore of Rajasthan are also called as Solonchaks. Colour of this soil is dark grey to pale brown. Water table is sometime close to surface. Cultivation is not possible due to the impeded drainage and high degree of salinity. The only vegetation consists of some salt tolerant grasses and shrubs.

Formation of soil is called pedogenesis. Soil formation is the process of soil formation from its parental material. In most of the cases colouration, mineral composition and texture of the soil is determined by its parental material. In addition to the soil parent material, soil formation is also dependent upon other prevailing processes like climate mainly temperature and rainfall.

Aeolian soil is the wind deposited materials that consist primarily of sand or silt-sized particles. These materials tend to be extremely well sorted and free of coarse fragments. CaO content in such soils varies from 1.0-1.5 per cent.

Formation of soil is called pedogenesis. Soil formation is nothing but the process of soil formation from its parental material. In most of the cases colouration, mineral composition and texture of the soil is determined by its parental material. In addition to the soil parent material, soil formation is also dependent upon other prevailing processes like Climate, Relief etc.

Desertification is a type of land degradation in which a relatively dry area of land becomes a desert, typically losing its bodies of water as well as vegetation and wildlife.

Cyclonic rainfall Mediterranean sea,

Summer Season, Winter Season, Rainy Season all are the seasons of Rajasthan.
